(Again) Very nice shots Sven!!
"Ice flowers" on the window. Must have been years since last I saw those. Really beautiful. You should think of a better isolation though....
Poor Sven, has to live in an ice cold room .
Ivan

thanks hiroshi and ivan!
As a child I saw these frost pattern at the inside of our windows.
This is my best isolated window, so the pattern is outside now!
These shots look like artificial pictures to me, like relief in photoshop. But sunlight, just touching these structures and a blue sky is enough for nature!
Sven

Jim, maybe you get a nice pattern of hoppers some day.
It's a matter of speed!
Sven

these were very unusual patterns for me.
This is a "standard" pattern (canon A70).
It is quite difficult to shoot these structures, you need a special light and time. There has to be a dark or blue background and you need a special angle to the object - DOF is waiting to kill the results - any advice??

thanks mtngal,
I was on the warm side of this window! My car has nice "ice flowers" sometimes, but trembling in arctic temperatures is not the right prerequisite for such macros! But I have to train this, I am dreaming of snow flakes......
